I'm willing to bet you're a freshman or in high school. Why do you want a double major anyway? It won't get you any points when applying to physics grad school. All they care about is if you're a physics major.
If it's because you really like math, don't worry, you'll learn plenty math as a physics major. You don't have to commit to picking up a whole major and lengthen your degree just because of that interest, especially if it's moot in the endgame. Consider taking a some math as electives or picking up a minor.
Engineering is a little different than physics. If you're sure you want to be in the middle, consider schools that have an engineering physics or applied physics degree. Just keep in mind you're strongest for a PhD in physics with a physics BS. I know two people that did the physics+math and really, it made them know more math, but it didn't make them better physicists than the vanilla majors.
